"Never again" is a phrase that still resonates decades after the 20th century holocaust in which millions of Jews, Christians, and others perished at the hands of their persecutors. "Never again" should mean the same for Jews, for Christians, and for every other victim of the holocaust, as well as for every attitude that generated the circumstances of the holocaust.
When "never again" is sliced and diced so that it is used only in reference to one segment of the holocaust victims, one is certain to have a reiteration of the circumstances of the holocaust in the 21st century and beyond. Our Lord God Almighty reminds us that we should do unto others only as we would have done to us, that we should love our neighbor as ourselves, that we should hate what is evil and cling to what is good, and that we should love the Lord our God with all our heart, mind, soul, and strength.
The Lord God Almighty El Shaddai
